" SEPARATOR FO'R PECAN AND OTHER' NUTS.

SPECIFICATION formingpart of Letters Patent No. 271,815, dated February '6, 1883 Application filed October 17, 1882. (No model.)

To all whom it may concern:

Be it known that 1, JOHN H. DOLMAN, of

' Albany, in the county of Shackelford and- State of Texas, have invented a new and useful 1m provement in Separators for Pecauand other Nuts, of which the following is a full, clear, and exact description.

This invention is more particularly designed for separating and removing the leaves, hulls, and other trash or extraneous substances from pecan-nuts when gathering them.

The invention consists in a machine provided with an inclined bed of parallel positively-driven rollers geared to rotate toward each other from above in pairs, and arranged at a suitable distance apart to allow of the leaves and other refuse falling through between them, but conducting the cleansed or separated nuts over them for delivery over a back board, orotherwise, away from the leaves and refuse, and where they may be put into sacks, or be otherwise collected. A hopper arranged over the upper or highest portion of the inclined bed of separated rollers provides for thestead y supply or feed of the nuts, with the leaves or other substances accompanying them, to the roller-bed, substantially as hereinafter described.

Reference is to be had to the accompanying drawings, formingpart of this specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a vertical section of the machine on theline mm in Fig. 2. Fig. 2 is a plan of the same with one-half of the hopper removed. y

A is the frame of the machine, which may be ot'box form or any other suitable construction, and which is fitted with a hopper, B, within which the nuts, together with the leaves, hulls,"and other trash or refuse collected in gathering the nuts, are thrown.

Arranged below the hopper B, and beyond r it, is an inclined bed of parallel rollers, (J G,

of which there may be anydesired number, but four--that is, two. pairs, G Gare here shown. These rollers are arranged at such distances apart and of such diameters that while they will freely admit of the-leaves and trash to clear them of leaves and other substances, 6

and to carry the cleanings through between them. The highest one of these rollers isimmediately under the hopper, and the lowest one next to the chute D. The inclination oft-he whole bed of rollers is not excessive, so that thenuts, in passing down over them, will be thoroughly cleaned before being, discharged over the chute or inclined board 1), for packing in sacks or otherwise. The leaves and refuse, being separately collected below the rollers, may be variously disposed of.

Power to rotate the rollers may be applied by a crank orhandle, G, to one of themyand' be communicated by the pinions E to the remainder of the rollers.

The rotation of the rollers, as described, is indicated by arrows in Fig. l of the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- V 1. In a separator for pecan and other nuts, the combination of a forwardly-inclined bed of parallel rolls arranged in pairs, with each roller-axis in a horizontal planeand at a suitable distance apart to prevent the nuts from falling between them, but allowing the precipitation of other matter, with means for rotating the rolls of each pair in opposite direc' tions, as and for the purpose specified.

2. The combination of the hopper B and chute or board Dwith theinclined bed of separated and positively-driven rollers G G,caused to rotate toward each other from above in pairs, essentially as herein described.

3. The combination ofth'e inclined bed of separated rollers O O, the gears E, by which motion is communicated to said rollers to rotat-e them in relation with each other, as dee 27mm scribed, the hopper B, and the chute D, subbe projected above said chute, while the refuse stantially as and for the purposes herein set will be arrested and guided under the rolls, as 10 forth. shown and described.

- 4. The combination, with a forwardly-in- JOHN H- DOLMAN.

' clined bed of rolls, of a chute, D, arranged on an inward incline in front of and under the Witnesses: last and lowest roll, and extending up about THOMAS. HALL, the height of said r011, whereby the nuts will I SAML. SPEARS.
